For starters this is the easiest to use air purifier, you simply plug it in and hit the power button. It immediately scans the air and tells you the percentage your air is at and then starts running. If the air is bad you can hit the button to scroll through which particles you have the most of and how long it will take to clean. You can also adjust the fan to go higher as well. It's super quiet so barely noticeable as it runs and it's so small you can easily move this around from room to room. I prefer to use it in the kitchen as it really helps with smoke/grease after cooking. The filter lasts up to 12 months so there is almost no maintenance. Overall I highly recommend.
